HEATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 324,074, dated August 11, 1885.

Application filed November 13, 1884. (No model.) Patented in Belgium August 16, 1884, No. 65,901; in Sweden December 24, 1884; in France January 12, 1885, No. 164,022; in Germany February 5, 1885, No. 30,335; in Austria March 1, 1885, No. 39.833 in Spain March 11, 1855, No. (3,578, and in Norway May 19, 18:5.

T 0 all whom it may concern:

Be it known that I, MARnvUs J AN ScHUUR- BEQUE Bonita, of Zwolle, Province of Overyssel, in the Kingdom of the Netherlands,have invented certain new and useful Improvements in HeatingStoves, of which the following is a specification.

This invention has reference to an improved heating-stove which combines the advantages of a common stove and a base-burning stove.

In the accompanying drawings, Figure 1 represents a front elevation of my improved heating-stove. Figs. 2 and 3 are respectively a vertical central section on line or m, Fig. 1, and a'horizontal section on lineg y, Fig. 2. Fig. 4 is a vertical central section of a heating-stove with an exterior air-heatingjacket; and Fig. 5 is a vertical transverse section of a modification of my stove.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, a represents the cylinder or body of my improved stove,which body is made of cast or wrought iron, and closed at the top by a detachable lid, a. If it be desired to heat water on the stove, the body a is provided below the lid a with a horizontal partition, (1, having a central open ing and a detachable lid, d. At the interior of the cylindrical body a is arranged a vertical transverse partition-wall, e, which extends downwardly into the firepot 7c. The partition is made of segmental shape and divides the body a of the stove into two parts-a larger filling-shaft, f, and a smoke-flue, g. The fillingshaft f is closed at the upper end, but communicates by an opening, it, and pipe h with the upper part of the stove and the smokepipe. The pipe h is opened or closed by a pivoted lid or valve, i. The lidz' is operated from the outside by a connecting-rod passing through the stove, and a handle at the outer end of the same.

In the modification shown in Fig. 5 the valve r is arranged directly on the opening h and operated from the outside by a link-connection with an oscillating handle, so as to close the smoke-flue y when in raised position,

while it closes the opening when in lowered position.

The cylindrical body a of the stove is provided with a tightlyfitting supply-door, u, at the front, which is opened for charging the stove.

When the stove is used as a common stove with a direct draft, the valve 1' is opened, while when the stove is used as a base-burning stove the valve z is closed, in which case the fire-gases are conducted through the flue g to the smoke-pipe. The door a has to be tightly fitted, so as to avoid the escape of smoke. \V hen it is opened for charging the stove with fuel, the valve i is also opened, so that the smoke can pass off freely through the openi ngs h to the smokepipe. The transverse partitiorrwall e is rigidly secured in position by a vertical stay, Z, that divides the flue 9 into two sections, as shown in Figs. 2 and 3.

If the body a is made of cast-iron, the segmental partition 6 may be cast integral therewith; but when the stove is made of wroughtiron the partition e has to be riveted to the same. In this case the connection of the partition e with the wall of the body should be made as narrow as possible. Below the smokepipe is arranged an upwardly-projecting inclined deflector, that serves for the purpose of conducting the fire-gases in upward direction before they pass to the smokepipe, so as to utilize the heat of the same in a more effective manner.

In the lower part of the cylindrical body a is arranged the fire-pot 7a, which is built up with fire-bricks m. The diameter of the firepot is is made somewhat smaller than that of the body a, so that between the wall of the body a and the fire-pot is formed an annular space by which air can pass in upward direction. When no fire-pot is used, the fire-bricks have to be made higher at the rear part of the stove, andare supportedat some distance from the wall of the body, so that an annular airspace is forxned between the same and the fire-, bricks for the circulationof the air. At the bottom of the fire-pot is arranged the grate o, 5

[o chimney.

pan 0. The ash'pit b is located in the base I) of the stove, and tightly closed by a hinged door, 1). The ash-pit is further provided with a register, q, by which the supply of air to the stove is regulated. The air which enters through the register q passes through the ashpit and grate to the burning fuel, from which the products of combustion are conducted through the smoke-flue to the smoke-pipe and The unburned fire-gases are mixed in the smoke-flue with the unburned air passing through the joints of the fire-bricks, and with the air heated in its passage through the annular space between the wall of the stove and the fire-pot, and are thereby completely burned. Actual tests have shown that an almost perfect combustion of smoke takes place, especially when the fire has been properly started, as the proper quantity of air required for the proper combustion of smoke is supplied through the annular air-space around the firepot to the flue g.

The fire is started in the stove in the usual manner, and the stove is quickly in condition for heating, as the small grate requires but a small quantity of fuel to cover it entirely and cause thereby the heating of the air and the more perfect combustion of the fuel and firegases.

In Fig. at the stove is inclosed by a sheet-metal casing, a which serves for ventilating purposes, and which is for this purpose connected with an air supply pipe, (shown in dotted lines,) through which the air is drawn in from the outside.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with the body of a heating-stove, of a vertical segmental parti tion extending into the fire-pot and dividing the interior of the body into a filling shaft or magazine on one side and a cresccnt-shaped combustion chamber or flue on the opposite side, a plate covering the top of said fillingshaft and provided with a dampered opening, an exit-flue leading from said body near the top thereof, and an inclined plate attached to said body between said exit-flue and said filling-shaft, said plate being located over said crescent shaped flue, substantially as described.

2. The combination, with the body of a heating-stove, of a vertical segmental partition extending into the fire-pot and dividing the interiorof said body into a filling shaft or magazine on one side and a crescent-shaped combustion chamber or flue on the opposite side, said crescent-shaped combustion chamber or flue being divided by a vertical partition extending between said segmental partition and the body of the stove, a plate covering the top of said filling-shaft and provided with a dampered-opening, an exit-flue leading from said body near the top thereof, and an inclined plate attached to said body between said exitflue and said iilling'shaft, said plate being located over said crescent-shaped flue, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
